A word from Bailee, the 'Twisty from American Horror Story' costume creator:

Twisty was so fun to make! The shirt and pants were sewn out of bed sheets, since the character in the show has lose, free-flowing clothes! The mask was hand carved from EVA foam, and the spikes were made from spider webs and cotton balls! The costume cost around $15 to make, including face paint! I tattered the clothes to give it a worn look with soot from an old fireplace!
